摘要： An analysis method and apparatus are disclosed for treating polymer granules at least part of which comes from post-consumer recycling, in which a flow of a process gas is purified from contaminating vapours by traversing, in sequence, first a dust collector filter that retains the solid particles contained in the gas, then a first side of a gas/gas heat exchanger in which the process gas surrenders heat, then a condenser in which the process gas is cooled to below the boiling point of the contaminating vapours to form condensate, then a second side of said exchanger in which the process gas recovers a part of the previously transferred heat, to then enter a container where the polymer granules are treated.
